Radio communication method, radio communication apparatus, and radio communication system
First Claim
1. A radio communication method for use in a radio communication system which includes first and second radio communication apparatus and in which the first radio communication apparatus transmits data to the second radio communication apparatus, the radio communication method comprising:
- transmitting, by the first radio communication apparatus, a message including data different from control information and source information indicating a source radio communication apparatus as a transmission source of the message to the second radio communication apparatus at a time point capable of transmitting the control information used for a process for establishing connection when the connection is not established between the first and second radio communication apparatus;
receiving, by the second radio communication apparatus, from the first radio communication apparatus the message transmitted at the time point when the first radio communication apparatus is able to transmit the control information; and
extracting, by the second radio communication apparatus, data different from the control information from the received message only when the source radio communication apparatus indicated by the source information in the received message is registered in the second radio communication apparatus.

Abstract
A first radio communication apparatus includes a controller and a transmitter. The controller determines timing capable of transmitting a control parameter used for a process for establishing connection to a second radio communication apparatus when the connection is not established between the first and second radio communication apparatus. The transmitter transmits a message including data different from the control parameter to the second radio communication apparatus at determined timing. The second radio communication apparatus includes a receiver and a data processing unit. The receiver receives from the first radio communication apparatus the message transmitted at timing at which the first radio communication apparatus is able to transmit the control parameter. The data processing unit extracts data included in the received message.

6. A radio communication apparatus to receive data from another radio communication apparatus, the radio communication apparatus comprising:
-
a receiver configured to receive a message including data different from control information and source information indicating a source radio communication apparatus as a transmission source of the message, transmitted at a time point when said another radio communication apparatus is able to transmit the control information used for a process for establishing connection from said another radio communication apparatus in which the connection is not established between said another radio communication apparatus and the radio communication apparatus; and a data processing unit configured to extract data different from the control information from the received message only when the source radio communication apparatus indicated by the source information in the received message is registered in the radio communication apparatus.
